HENRY O. WEITZEL AND EUGENE R. PRUITT,

OF BALTIMORE, MARYLAND.

Specification of Letters Patent.

Patented March 13, 1906.

Application filed May 16, 1905. Serial No. 260.669.

Be it known that we, HENRY O. WEITZEL and EUGENE R. PRUITT, citizens of the United States, residing at Baltimore city, in the State of Maryland, have invented new and useful Improvements in Automatic Clean- Sweep Waste for Outside Hoppers, of which the following is a specification.

Our invention relates to an improvement in water-closet valves and fixtures, the object being to automatically release water which would otherwise remain in the flushing-pipe, whereby to completely drain the latter and prevent freezing of the pipe.

With the foregoing object in view our invention comprises a connecting-pipe which extends from the flush-pipe to the trap, said connecting-pipe provided with a constriction of sufficient size to drain the flush-pipe and at the same time to prevent interference of the flow of water through the flush-pipe at the time of flushing the bowl.

Our invention further consists in certain novel features of construction and combinations of parts, which will be hereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a side elevation of a closet. Fig. 2 is a plan view with parts broken away, and Fig. 3 is a detail partly in section.

I after flushing,

A represents a bowl; B, the usual trap.

C is the main, D the flush-pipe extending therefrom to the bowl, and E is the ordinary flush-valve.

The letter F indicates the connecting-pipe, which extends from the lower end of the flushpipe, preferably at the point where the latter leads from the main, to the trap. This connecting-pipe has a constriction preferably cone-shaped therein, as shown at 1, and the purpose of this construction is easily apparent. The primary object of the connection is to drain the flush-pipe and bleed it of any Water which would otherwise remain in it I the flush-pipe naturally remaining filled at all times but this connecting-pipe drains or bleeds it so there is no danger of freezing. The constriction 1 is for the purpose of retarding the flow, so that in flushing, although the connecting-pipe is always opened its opening is so much smaller than the flush-pipe that the amount of water issuing therefrom is not appreciably affected by the presence of the connecting-pipe At the same time the constriction affords a vent of sufficient size to insure the slow but complete bleeding of the flush-pipe.

Thus it Will be seen that in a very simple manner we have provided a fixture which may be applied to any water-closet system now in use, it being perfectly effectual in performing its functions.

More or less slight changes might be resorted to in the form and arrangement of the parts described without departing from the spirit and scope of our invention, and hence we do not wish to limit ourselves to the exact construction herein set forth but,

Having fully described our invention,what we claim as new, and desire to secure by Letters Patent, is

The combination with a bowl and flushpipe, of a connectingpipe secured at the lower end of the flush-pipe and bowl, said connectingpipe having an internal coneshaped constriction formed in one end thereof, whereby to slowly bleed the flush-pipe of its contents after flushing the bowl Without interference with the ordinary flushing of the bowl.

In testimony whereof we aflix our signatures in presence of tWo subscribing Witnesses.
